Title: Surface protective film for iii-v compound semiconductor
Inventor: FUJIEDA SHINJI
IPC: H01L21/318
Filed: 1988-12-22
Abstract: PURPOSE:To obtain an amorphous and high-resistance film by a method wherein Al, P and N are used as the constituent elements of the film and the content of P of the film is set at 0.2 to 2% of the content of N of the film. CONSTITUTION:If P is added in an AlN film by 0.2% or more of the content of N of the film, the film is turned into an amorphous film. For example, it is known that an AlN film deposited on a GaAs (111) B plate is a polycrystal of a (0001) orientation from a measurement of its X-ray diffraction, but by adding P in the film, the peak of the X-ray diffraction disappears and the film ceases to show a crystalline property. Moreover, if the content of P of the film is set at 2% or less of the content of N of the film, a fact that the interface reaction of the film with a semiconductor is hardly generated can be also verified from a measurement of an SIMS(a second ionic mass analysis) in respect to a GaAsInP. In such a way, by setting the content of P at least at 0.2% and at most 2% or less of the content of N, the resistivity of the film is reduced only a little and the film can maintain a high resistivity.

Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor accelerometer which can prevent its flexure part from being damaged even when it is dropped mistakenly. SOLUTION: An accelerometer is provided with a body 1 in which a tube body 11 comprising a tube axis 11a is installed, and in which a flange 12 installed on a placement face 12a so as to protrude to a direction nearly at right angles to the tube axis 11a from a base end part 11b of the tube body 11 is placed on an apparatus 3 whose acceleration is to be detected and with a semiconductor sensor part in which a flexure part used to generate a flexure when an acceleration is applied is installed, in which the flexure part is cantilever-supported and which is housed in the tube body 11 on the side of the base end part 11b. On the basis of the flexure of the flexure part, the semiconductor sensor detects the acceleration applied to the apparatus 3 to be detected.  In this case, an impact absorption part 12b which absorbs an impact force at a time when the accelerometer is dropped is installed at the flange part 12.

Title: Conveyor equipped with rotating hanger
Inventor: TAKEDA SHUNZO
IPC: B65G47/84
Filed: 1988-12-26
Abstract: PURPOSE:To prevent nonuniformity in painting work etc. by equalizing the number of revolutions of a clutch shaft with that of the shaft of a sprocket for driving a conveyor chain for rotating a hanger and adopting a single position clutch. CONSTITUTION:Conveyors 1 and 1' and a first conveyor chain 7 for rotating a rotating hanger are driven by a single motor 11. By using a clutch 14, the conveyors 1 and 1' are stopped, while the chain 7 is driven. In addition, the number of revolutions of the shaft of the clutch 14 is equalized to that of a sprocket 19 for driving the chain 7. With this, by adopting a single position clutch as the clutch 14, the conveyors 1 and 1' are stopped by the clutch 14 at any position. When the conveyors 1 and 1' are restarted, the conveyors 1 and 1' do not start their conveying work immediately by their restarting but they start their transfer work when the phase of a hanger 6 becomes the same phase as what it was when the conveyors 1 and 1' stopped. With this contrivance, nonuniformity is painting work can never be generated.

Filed: 1993-11-29
Abstract: PURPOSE:To improve the smoothness of opening and closing operation of a back lid in the tape cartridge equipped with a front lid, a top lid and the back lid for opening and closing a tape loading pocket. CONSTITUTION:The front lid 17 turning to open it upward in the upper direction of the pocket 6 around a turning shaft 23 is disposed in front of the pocket 6. The front lid 17 is pivotaly fitted to the top lid 19 to be freely turnable around a shaft 30. The top lid 19 is pivotaly fitted to the back lid 20 to be freely turnably around a shaft 36. When the front lid 17 is turned to open it upward, the top lid 19 and the back lid 20 are retreated toward the upper part of the pocket. A partial circumferential surface part 11a of a boss 11 having a reference hole 9 is protruded backward in the pocket 6, therefore an upper part area 12a of this partial circumferential surface part 11a is made smaller than a lower part area 13a in outer diameter. Consequently, when the back lid 20 is opened and closed, the lid 20 does not interfere with the partial circumferential surface part 11a.

Title: Method for injecting carbon dioxide into ground under pressure
Inventor: HORIZOE HIROTOSHI
IPC: C01B32/50
Filed: 1992-12-07
Abstract: PURPOSE:To inject CO2 into the ground under low pressure. CONSTITUTION:The CO2 is introduced into a CO2 booster 2 from a line 1, boosted and then introduced into the upper part of a pipe 9 piercing the ground from a CO2 forcible feed line 5. When the liq. CO2 is introduced from the line 1, it is passed through a heat exchanger 4 and heated. Water is supplied from a line 6, pressurized by a pump 7 and introduced into the pipe 9 from a line 8. The CO2 from the line 5 and the water from the line 8 are mixed in the pipe 9, and the sp.gr of the fluid in the pipe becomes higher than the CO2 alone. Accordingly, the static pressure generated by the fluid in the pipe is increased at the tip 14 of the pipe 9 in proportion to the density. Consequently, the CO2 from the line 5 at a low pressure is forced into the aquifer 13 under pressure from the tip of the pipe 9.

Abstract: PURPOSE:To make the turning operation of a vehicle smoothly perfomable by making a hydraulic fluid discharged out of a variable displacement pump so as to be fed to each motor being opposed on the basis of operation of a steering according this steering operation. CONSTITUTION:If a steering is operated for rotation, rear wheels are rotated, while this steering angle is detected by a detector 16, and with this detected value, a central processing unit 17 moves each spool of flow control valves 12a, 12b, whereby a flow rate of hydraulic fluid flowing into a motor 7b at the right is restricted. With this constitution, a quantity of hydraulic fluid flowing into a motor 7a at the left increases, and rotational speed of a left front wheel 6a goes up, while rotational speed of a right front wheel 6b goes down so that a vehicle is curvedly advanced to the right. When motion of a backward lever 22 is detected by a position sensor 23 and it is inputted into the central processing unit 17, this unit 17 outputs a signal to selector valves 15a, 15b, thereby making the hydraulic fluid so as to flow in reverse.
